. Be it known that LAUGUST HdoHLnnrnrn. of the city-of St. Louis, inthe State of Missouri, have invented a certain new and use ful Improvement in Water-Filters, of which the following is e `full, clear, 'end exact de scription, reference being had to the accompenying drawings, forming part of this speeiieation. l

My invention relates. to certain improvements in watenlters of the general class shown in my Patent No. 510,348, dated De'- Ycember 5, 1893; and my present invention consists in features of novelty, hereinafter fully described, and pointed out in the claims.

Figure I is a side elevation of my improved Water-filter, part of the receiving-tank being shown in section. Fig. His en enlarged View of the filtering-tank end eonnecting-pipes,tlie parts .being in section. Fig. III is e transverse section taken on line III III, Fig. Il. Fig. IV is an enlarged detail view illustrating the manner of connecting the cap or hood ,of the filtering-tank. Fig. V is en enlarged'i vertical section of the supply-valve. l Referring to the drawings, 1 represents the filtering tank or chamber, supported on e suitable base 2.

3 represents the clear-Water cylinder or storage-tank; supported on e suitable bese 4- or otherwise, Isind 5 represents an auxiliary tank, supported on the bese 6 or otherwise.- At thloiiver end ofthe cylinder or chamber 1 is a cheinbe'rl 7', the bottom 8 of which is secured in place by bolts 9, cest in the lower portion 10 of the cylinder l.. 1l represtentsl the mein supply-pipe' from themweternmen, or other sonrcevoi supply, v end which discharges preferably intothe upper end of the filtering-tank. The inner end of the pipe 11, Within the tank, is provided with e heed, consisting of en inner ring 12, and en outer ring 13, (see Figs. 1I end IIL) both of which receive water from the pipe 11.

These rings ere perforated at ,their lower surfaces, es shown in Fig. II, and through these"A y perforetionsthe water Hows in streems,which are directed against the outer surfaces of the s filtering blocks or stones 14, end tend to keep the outer surfaces of the stones washed clean f of mud and sediment.

I ez'tending into the lower end of the hlteringtank, and communicating with e perforated hollow ring ortube 16. This branch 15 is provided with a valve 17, end the pipe 11 is 'provided with a valve 18. l

lVhenit is desired to wesh out the f l'ltering-tank, the valve 18 isclosed end the valve 17' is opened, when Water will be discharged through the ring 16 and' sprayed over the bottom of the filtering-tank, from whence it and 'the ruud will be discharged through e ssv supported within the iiltering-tenk by meansI l of pipes'l, having smell perforations I22 within the filtering-stones, through which the filtered Water passes from the interior of the I stones into the chamber 7, es shown by the'` arrows, Fig. Il.

disks 23, threaded onto or otherwise secured to the pipes, end against which (with an in# tervening gasket, if desired,) rest'the lower ends of the stones. At the other ends of the pipes are cup-shaped disks 24, tting loosely on the pipes, and which beer (with interposed gaskets, if desired, against the upper v ends of the stones.

Over the disks 24 are nuts 25 on the pipes 21.

[nntspthe, iiltering-stones are clamped between the disks 23end2/i`, and owing'to tliev concave shape othe disks and the eonve'x By tightening the f l ends of the stones, the letterl ywill be righted up into vertical position, es the nuts 25 are' tightened. IThis manner of connecting the stones to the pipes is, not, however, claimed by this lapplication, es it is a feature shown end-.described in 'my spplicetionferiel No.

It frequently happens that short pieces 'of stone can be cheaply obtained, as, for im stance, Where one end of e stone is faulty or broken, end to provide for the use of Vsuch Lfhort nieces, I employ rings 26, which are IOO .Water into the top of the tank.

'wedge-shaped in eross-'Seetion, as Shown in Fig. Il, By ueing these rings between the Sections' of a stone, a tight'joint is ,formed and the Stone afs a Whole is very strong and durable; the ends of the Seetions joining the rings being, of course, shaped to conform to* theI Sha-po of therings. If preferred, gaskets may he placed between the rings and 'the ends of the Sections.

The clear water or storage tank 3 is eonneeted to the chamber .7. of the iterilrhtanli hy means of a pipe 28, from which rlsee a l'ertiel pipe 29, that! discharges, the Clear The tank 3 may be loeated ai; any Convenient place, and at any desired dista-,noe from the filteringt-ank, and it may he dra-ined into the pipe lt) by means of a pipe Btl, eonneeting it with the pipe lil through the pipe 2S; the pipe 28 haring a valve Si, and the pipe ii() havinga valve Si, which are to he opened when the Storagewtank is to he drained intothe pipe 19.

The Clear water is drawn from the tank 3 through means of a pipe 313, einineetingwit-h the pipe t, and provided with a valve '34, which would he rinsed when the tank b iS to be drained into the pipe iti. provided with a peteork 35, for admitting air to the I'anlt Il when the latter is'to be drained, and the pipe 2H is Further provided with a eheeliwalre ilo, to prevent air from eeeaping hai-lc throng-h the pipe 2Q, when it iS Compressed in the tank 1i to a degree eqnalingg, or in ext-ess ot' the pressure ol' the Waterifroin the lilnrngianli l. 'lhe tank 5 is (fennel-ted to the pipe 2o through means of a pipe IST, upon n'hieh the tank is supported' on the haue VyA As the waierpasses from the interino-tank to the tank Il, 'a portion, ol' it ent ers the auxiliary cylinder 5, and oinprel se 4 the air therein until the air-pressure eguale the pressure ot the water. The water then simula in the anxiliaur eylinder, under the tension ol' tho air-pressure, and when the water-pressure in the Supply-pipe l1 ist redueed, the air-pressure in the eylinder 5 will -toree the unter therein haelt, through the pipe-hv il? and and through the ohaniher T and piper ilout throng-h the Small pert'orationn 2; in the piper'. 2l, and through the iiltering-slones, ihm` cleansing the stones hy littered Watan' paSsing' through them in the opposite direction from whieh it passes during the ilterinfl process. The small pertoratione` 2t retard a rapid reflux'. of the Water, so as to preyent danger ot' breaking the stiiines. ',l`his.4rellux ot water takes plaee eaeh time there is a reduction of water in the supply-pipoll, and the cylinder 5 is lilled ae'aineaeh frimeifhe pressure in the pipe ll' resumes its normal eoi-ulilion. ly providingl the auxiliary erlinder 5, the stones are thus eleaned without diminishing the supply el' water in the -.lear\rater tank Il, or without diininiehine; the presmireotf the eonipressed nir `n he tank ii.

lt il indes-iard anytime to uliliZet-heairpressnrein the tank 3, through the cylinder 5, it may be dnethrough means of a pipe 3S which connects the upper end et the ta withv the eyiincler 5', and which is pro with a Valve 39.` The cyiinder 5 is pro i 'Y with a gage 40,' and itis preferahlyeonneetee. to the tank 1- by mea-ns of a pipe or hose provided with Valves 42, so that air may pees from the tank 5 into the upper end of th tank l, when desired, and Vice versa, the emi ot' the pipe l Within the tank l being eleeed by a loat and valve 3, when the Wat-er :in the tank l reaches 'the oat, (see Fie. il) thee the tank l i'ntethe cylinder 5, without ing through the filtering-stone. V

The Captor dome ifi of the tank l is preferably secured in piace hy means of rods 5, (see Fig. 1L) pivoted (3i-hinged at lli to the top ring l? of the tank 1, the bolts 5 fitting in notches in the ring 7, and in notches formed in the outf-turned ange of; the ea p it, and the holt-s having nuts e8 on their upper ende off which the feap is rawn lawn tightly in plane. By loosening on the nu S the holte are al lowed to dran hack on hinges, it?, and the eap ein to the interior of the tank` lil (see il and Hi) represents a gasket or packing-ring between the Cap etA the taai-1 and the ring 4,7, to inaure a tight; joint.

In Fig. w I have shown the eap hinged to `the ring -t-'at 50,50 that the rap ean he opened out on this hinge w ien 'the holte 45, are re mowed.

'he aten] 55 ol thiff` valve is threaded al 5U into the housz'ii oi the valve. The lower end ot' 'the Stein is formed with a eonieai point 57, Seated o\ er a port or pasiiage 5S in the valve proper 5h. The Valve 559 is Seated at (ill in the honaing'. 0n the lower end ot the stem 55 is a link or eollar f'l, litiingn'ithin a hollow neel; or t ula? U2, which is threaded onto the Yalre 5o.

When it is desired to admit a. small iltnrol" water through the valve, the Stein 55 run liaek Tar enough to carry the Conil-ai point ot' thesein 55 away from the valve 5t), and then all the. water that nlll pass through the pori ien he removed to allow necesa 5S (the water entering through the `ide of v 59 fwill be raised from its seat, allowing o.-

tree open passage of water through the filter.

The Valve construction also oiords etree reflux-of 'water through the volte w ieu the Stem 55 is raised from the valve 59, us iue Water in ite return through the eide IB of the valve acts to raise the valve from its seat and pese freely through.

For the purpose of causing en eutonmtie reduction in the pressure of Water ou the supply side of the filtering-teni: l, so that the pressure of-Warter on the discharge eide of the iilteringtauk will cause the Water to 'be foroeclloe-elt through the iilte1ing-stones,

l employ a tank 70, with the bottom oi' which connects a Waste-pipe '71, provided with :am ordinary Siphon 72 within the tank.

73 is a pipe leading from the supply-pipe l1' between the Valve l'md the toni; l to the tank 70. On the inner ond of this pipe, Within the tank, is an ordinary oat-valve 7l.

75 is a pipe leading from the pipe- 73, and which is preferably prei/'ideal with it vulve 7 7 7 is o @up mounted on o rook-shaft 78,115 which it is supported Within the box.

79 is a eounterbalaneeoveight ou the eiiot 78.` r

The operation is oe follows: The Water runs into the tank 70, through the pipe '73, until the tank is filled to about the extent shown in Fig. I. The iloot tlieu closes the Valve 7i and prevents e further passage ot' Water into the tank, through the valve. During this time tliewater is passing through the ltering-ta-nk, and o small portion of Water is passingthrougli the pipe 75 into the cup 77. Vhen the cup 77 is full, or is partially filled and overbalanoes the Weight 79, the cup turns over and ie dumped into the 'tank 70, This operation continues until the Water in the tank reaches the top of the Siphon, and. then the Water flushes out of the tauilc, permitt' g the float-valve Mtn open. Ae soon as the if ive 7 opens, the Water instead of passing through the iltering-ta1k l, passes through tlie pipe ipvinto the tant: 7l), thus removing' the pressure from the supply side of tlie iilteringtouk, so that the preesure on the discharge eide of the filteringtonl; will cause a beek iiow of water through the iiltering-Stones, to clean them,

By connecting the pipe 73 with the pipe l1 between the Valve 1S 2mal the tout: l, a oom- ;ipziratively smell amount of Witter posses through pipe 73 to what 'would have to pass through this pipe, to. entirely remove the preeuure from the supply si de, to what would through iid the pipe connect With the supplypipe ll loeol; of the mite i8.
